Answer:
Potassium is the only element with 19 electrons.
Explanation:
Explanation:
The given data is as follows.
50 ml of 
, 50 ml of 
And, it is known that at STP 1 mole of a gas occupies 22.4 L. Hence, moles present in 50 ml of gas are as follows.
(As 1 L = 1000 ml)
= 
moles
So, according to the given equation moles of reacts with moles of .
Hence, moles of 
is equal to the moles of and .
Therefore, moles of = moles
1 mole of = 22.4 L
moles = 
= 50 ml of product
Thus, we can conclude that 50 ml of products if pressure and temperature are kept constant.
Answer:
The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
Explanation:
This added movement tends to make the bonds between sucrose molecules easier to overcome.
Hope it helps :-)
Answer:
Los habitantes del planeta con una atmósfera superior a 5,1 atm de la Tierra, no estarían nadando en ríos de dióxido de carbono líquido
Explanation:
De las tablas de datos termodinámicos, la presión a la que el vapor de dióxido de carbono está en equilibrio con su estado líquido a una temperatura ambiente de 25 ° C es 6,401 kPa, lo que equivale a 63,17296 atm.
Por lo tanto, a una presión de 5.1 de la atmósfera terrestre, el dióxido de carbono es completamente gaseoso y los habitantes del planeta con una presión atmosférica de 5.1 atm de la Tierra todavía observarían solo hidrógeno gaseoso y no estarían nadando en ríos de dióxido de carbono líquido.
That table salt has a high melting point and mercury's melting point is low.
